This invention relates to a new and useful improvement in journal boxes,the object being to-construct a journal foruse especially in 'connection with railway rolling stock in which ,the box will. bey practically dustpr'oof androil tight, thereby enabling a chargeof lubricatingoil or grease to be ,in-A troduced, whereby the moving parts and contacting surfaces may be; well lubricated andrequire the introductionof a new charge of lubricant only at infrequent intervals.

In the drawings, 1 indicates an axle and 2 a car wheel arranged thereon, these parts being of a standard and well known construction.

3 indicates a journal box, preferably in the form of a casting open at each end and observing substantially a cylindrical form. The side walls of this casting are provided with laterally projecting lugs 4 constituting stops designed to co-operate with the pedestal jaws of arailway car truck in a manner well known.

5 indicates smaller lugs arranged'at intervals between the lugs 4, and preferably having flat surfaces for engagement with the pedestal jaws.

6 indicates the protuberance on the upper wall of the box and extending from a thickcned portion thereof to constitute a rocking 1922..l serialfNo. 558,070.-

9, said washer; being seated against webs 10` extending forwardly from the inwardly projecting flange 11, the aperture in said flange 11y being slightly larger in diameter than the axle atthispoint. y f 12 indicates a :shroud 'formed .on theinner end of the journal box casting, the space 13 j oroducedby the peculiar form: of the' shroud constitutingan enlargedoil orl grease chamber. The shroudlQ provides al bearingv surface 14, preferably elongated as shown, this bearing being undercut'on `its inner side so as to provideanincreased space j 'for thefgrease or liquid in the chamber 13..

lBearing'14 co-.operates with an antifriction'thrust bearing ring 15, preferably made of bronze or other suitable material, said thrust bearing'ring 15 being cast upon and interlocked with sa core ringcl, which is pressed or otherwise irninovably secured inposition on the,Y axle `1,and against the hub-ofthewheel. v 4

v 17 indicatesa thrust washer arranged between the ring 15. and the flange 11. This washer is preferably provided with a projection 18, shown in this instance, (see Figure 3) as a perforated lug, the purpose of which is to lift the grease vor'lubricant from the lower portion of the chamber `13 and' carry it to the top of the axle. This thrust washer thus becomes a lubricating ring whose function and mode of operation is well understood.

In the bore o-f the journal box and near its forward end is a semicircular groove or preferably recess 19 designed to receive the points or crowns of a star-shaped holding device 20.

This holding device is a rod or wire formed whereby the crowns'of the bent portions will seat themselves in the groove'lQ. To remove the holding device, it is only necessary to collapse the ends until the crowns are unseated. This holding device is designed to engage and hold in position an end closing plate 2l, which plate is of approximately the same diameter as the bore of the journal box. The plate may be provided with offset portions for the purpose of giving it strength and also providing a grease or lubricating space therebetween and thek end of the axle, this space being more than suiiicient to permit of end play of the' axle so that the axle will not come iny contact with the plate in such play. A seat is provided or a bolt head at approximatel'ythe center of the plate, said bolt extending ou'twardly and passing through a central aperture in a closing plate 22. This cap or clos-l ing plate is provided with an inwardly extending circular rib 23 which embraces the holding device 2O and the marginal edge of plate 22 is preferably machined to form a rabbeted joint with the en'd of a journal box. A castellated nut 2li co-operatesfwith a bolt 25 before referredy to to hold plate 22 in position. Should it be desired to gain access to the interior of t-he box, for purposes of repair or inspection, the nut is removed, leaving the plate 22 to be taken off. The holding device 20 may now be removed, whereupon the end plate 2l can be taken out. By jacking the box up, the rollers can be taken out and replaced.

For purposes of charging the box with grease or lubricant, I provide threaded openings leading into the chamber 13Y (see Figure l) which may normally'be closed by a plug 27. i u j t In Figures 3 and 4:, I havershown a modified form of holding devices comprising a plurality of segments 20a, which segments are spaced apart. so that they may be readilyV inserted into and removed from the groove 19.' 1When in operative position, these segnal box, an end closing plate arranged' therein, a sinuous holding device engaging said plate, and a. cap plate securedy to the end closing plate and bearing against the end of the box.

2. The combination of a journal box having acylindrical bore, an end closing platey fitting in said bore, a holding device seated in said groove adjacent to said endV closing plate, a cap plate seated against the end oi' the journal box, and means tor connecting the end closing plate and capl plate.

8. The combination of ajournalxbox, an end closing plate, a cap plate, a holding device seated within the journal box and ad# jacent to said cap plate, and means for moving said plates towards each other whereby said holding device is placed under shearing strain..

4. The combinationof a journal box, an end closing plate, a holding device in the form of afrod orwire bent inl the shape of a star, the points or crowns yof which-are' seated in the groove'in'the journal box, aca'pl plate' bearing against the endof thejournal box and provided with means for preventing.-

displacement of said holding device from said seat, and means for connecting said two plates together. l
